If I set fullscreen resolution to lower than my monitor native, when I start any game in windowed mode first and then alt+enter to go fullscreen, it remains black(in win. mode upon start it shows graphics ok). If I alt+enter to go back to windowed mode, it also remain black. Happens only in D3D, not OpenGL. R5186 x64, may possibly happen in newer too. Can anyone confirm?
